yaha: It si a great product. I had to buy a booster pump and a pressure switch because one needs a certain amount of water pressure from the street, for it to work properly (which I did not have in my apt) so be aware of this issue. But once you work with the pressure it works great. I gave it a 4 bc I had a previous system and I did not need the booster pump. On the other hand the older model I had was a 3 system and this one is a 5 (or 6) process system.

Michael McClendon: Purchased 2 Systems. Was able to install both systems in under 2 hours for each system. The systems install with great ease and the lines are color coded to make the install easier. The system makes water that has odor and bad taste much, much better. The system fills quickly with water pressure above 40 psi and above 60 psi the flow is extremely strong.

Amazon Customer: I had been putting off getting a system like this due to the need to drill a hole through the counter top. Well, that was easier than expected and the rest of the install took around 20 minutes. My wife couldn't be happier.

Kristyn Denneny: Water is now leaking all the time into the drain though the system backwash line ? need help as to why could it be a simple replacement filter needed

Juan Odetta Berg: Be sure to check each tube entire length. We had a leak at one end!

Alexandra C: I was really afraid buying this filter. I have been looking for a RO filter that re-mineralizes the water and adjusts the PH back to a healthy level. The price is so cheap for the unit I expected it to be junk. I opened the box and carefully inspected the parts to ensure quality. I do not want a filter that leaks and wrecks my house so I was very worried.

The quality is 5 stars the only thing I would like to see is better seals on the 3 main filters underneath you have to tighten them way to tight for plastic threads. I would also like more pressure how ever the only unit I saw with decent pressure was the Kinetico filter and it was 5 times the price.

I would strongly recommend this product. outside of a few minor improvements that could be made this is 5 stars across the board the water taste PH and how clean it is hits the mark every time.

I have it plumbed into my fridge and it works with my icemaker just fine without any other mods outside of a T fitting I had to buy and a shut off for the line.

Cindy: I am so happy about getting this. I read the reviews and when I received it, I pulled all the connections and made sure the tubing was cut straight, then reinstalled them. I have to say it has been a few weeks now and there have been no leaks at all. This was purchased because our well water was almost 900 TDS/ppm with an EC of 1.6 to 1.8. It tasted so bad, and we always purchased bottled water. This got my water down to 23 ppm and the EC bounces from 0.0 to 0.1. The water tastes great. I want to get one of these for my daughter. Her well water is similar to mine.
The only thing that could be a problem for some people is the tap. It has a very very slow drip. There is no way to correct it either. The drip forms and drops about once every 10 minutes. This does not bother me, but maybe someone else.
